Show images only

[emediastudios]

I have a code that displays all the files in a folder as well as a thumbnail image.

This is a page that allows my client the option to delete a image from his dir if it is no longer needed.

I was hoping that i could alter my code so that it only displayed images in jpg, jpeg, gif or png.

and if there is files or folders that are not of this format in the selected(../images) directory, not echo them.

Here is my code.

<?PHP 
$folder = "../images/"; 
$handle = opendir($folder);

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

#echo the files 
foreach ($files as $file) { 
   echo "<img src='$folder$file' alt='image' width='150' /><br />";
   echo "<a href='$folder$file'>$file</a> - ";
   echo "<a href=filedelete.php?file=$file>Delete this Image</a><br /><hr />";



} 
?>

MAny thanks.

 

Oh i have this code too, maybe i could use some code out of it and combine it with the upper code?

<?php
echo "<select name=\"file\">\n";
foreach (new DirectoryIterator('.') as $file) {
   // if the file is not this file, and does not start with a '.' or '..',
   // then store it for later display
   if ( (!$file->isDot()) && ($file->getFilename() != basename($_SERVER['PHP_SELF'])) ) {
      echo "<option>";
      // if the element is a directory add to the file name "(Dir)"
      echo ($file->isDir()) ? "(Dir) ".$file->getFilename() : $file->getFilename();
      echo "</option>\n";
   }
}
echo "</select>\n";
?>

I have imported a function into the code but am unsure how to call upon it

 

<?PHP 
//filter extensions
function valid_ext($file_name)
{
$valid = array("jpeg","jpg","png","gif");
$extension = strtolower(substr($file_name,-3,3));
return (in_array($extension, $valid));
}
///Directory Settings
$folder = "../images/"; 
$handle = opendir($folder);

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

#echo the files 
foreach ($files as $file) { 
   echo "<img src='$folder$file' alt='image' width='150' /><br />";
   echo "<a href='$folder$file'>$file</a> - ";
   echo "<a href=filedelete.php?file=$file>Delete this Image</a><br /><hr />";





} 
?>

I have no idea, i dont get any errors, just a blank page.

I added a filter  and array butim sure its all wrong.

Heres my new code.

<?php
//filter extensions
$file_name = $file;
function valid_ext($file_name)
{
$valid = array("jpeg","jpg","png","gif");
$extension = strtolower(substr($file_name,-3,3));
return (in_array($extension, $valid));
}
///Directory Settings
$folder = "../images/"; 
$handle = opendir($folder);

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

//Test Check
$Valid = false;
if(valid_ext($file_name))

#echo the files 
foreach ($files as $file) { 
   echo "<img src='$folder$file' alt='image' width='150' /><br />";
   echo "<a href='$folder$file'>$file</a> - ";
   echo "<a href=filedelete.php?file=$file>Delete this Image</a><br /><hr />";
} 
?>
